b2530a4c93 network: be more specific on port mismatch error 2019-09-16 16:32:04 +03:00

773ccc2b92 network: allow discoverer to reuse addresses
...and don't try to connect to the nodes we're already connected to.

Before this change we had a problem of discoverer throwing away good valid
addresses just because they are already known which lead to pool draining over
time (as address reuse was basically forbidden and getaddr may not get enough
new nodes).

46dc141c6c network: enlarge address request queue
Queuing one message is not reliable enough, the peer that gets it can fail to
actually make a request, so make this queue a bit deeper to have a higher
chance of success.

d3bb8ddf8f network: handle errors and connection close more correctly
This makes writer side handle errors properly and fixes communication between
reader and writer goroutine to always correctly unregister the peer. This is
especially important for the case where error occurs before handshake
completes as in this case we don't even have goroutine in startProtocol()
running.

76c7cff67f network: make node strictly follow handshake procedure

90e13debe4 network: implement getaddr sends and addr receival

be6c905e5d network: use and improve discovery mechanism for reconnections
This makes our node reconnect to other nodes if connection drops for some
reason. Fixes #390.

8d9bc83214 util: drop Endpoint structure, fix #321
I think it's useless, buggy and hides parsing errors for no good reason.

2fd782eee8 util: drop RandUint32()
I don't see anything useful in it, all the current users of it should just use
plain rand.Uint32() not limiting its output in any way.
